Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507686, here are decompositions:

13 + 507673 = 507686
19 + 507667 = 507686
79 + 507607 = 507686
97 + 507589 = 507686
163 + 507523 = 507686
337 + 507349 = 507686
373 + 507313 = 507686
397 + 507289 = 507686

Showing the first eight; more decompositions exist.
